This strata was very good. We particularly liked the spicy brown mustard. It added a very nice flavor. The only thing that I will change next time is the amount of egg. We prefer more an egg texture than bread, so I will try 1.5 the amount of eggs next time to see if we like that better.

Delicious! This was a mighty fine way to use up some day-old homemade sourdough bread I had laying around. I used Gruyère for the cheese and guess I should confess, I did add a tad extra. :) We loved it--thanks for posting!
